WATER-PURIFYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 769,749, datedSeptember 13, 1904.

Application filed November 5, 1903. Serial No. 179,387. No model.)

To all whovn it TII/II/Z/ concern:

Be it known that l, FREDERICK G. KUNn, a citizen of the United States,residing at the city of New York, borough of Brooklyn, county of Kings,in the State of New York, have invented a certain new and useful 1Vater-Purifying Apparatus, of which the following is such a full, clear,and exact description as will enable any one skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification.

The principal object of my invention is to so construct an electricwater-purifier that the water to be purified will be held between thetwo electrodes a sufficient length of time to insure a completepurification of the water.

Another object of my invention is to simplify the construction of thepurifier.

My invention consists, in part, in the combination, with a plurality ofconduits each having an inlet and an outlet, said conduits beingimperforate intermediate of the'inlet-s and outlets, of electrodesarranged in said conduits to leave free circulating-space for the waterbetween said conduits and electrodes, and electrical connectionsconnecting said electrodes and conduits with a source of electricalenergy.

My invention also consists in certain other novel features and detailsof construction, all of which are described in the followingspecitication and pointed out in the claims afiixed hereto.

1n the accompanying drawings, which illustrate one form of purifier madein accordance with my invention, Figure 1 is a side elevation alsoshowing the circuit diagrammatically. Fig. 2 is an enlarged sectionalview of two adjacent conduits, the central portion being broken away.Fig. 3 is a top plan view, and Fig. 4 is an enlarged section on the line4 4 of Fig. 2.

Like marks of reference refer to similar parts in the several views ofthe drawings.

represents a number of conduits, preferably made of metal pipe. Theseconduits 10 are parallel and are preferably arranged vertically, asshown in Fig. 1. Each of the conduits 10 is provided at its upper endwith l a T 11 and at its lower end with an elbow 12. The elbows 12 atthe lower end of the conduits are connected by means of nipples 13, asshown in Fig. 1. The Ts 11 are connected by means of nipples 14, exceptthe Ts of the outer conduit-s, which are connected to inlet and outletpipes 15 and 16, respectively. These inlet and outlet pipes '15 and 16are provided with valves 17 and 18 for regulating the flow of waterthrough the conduits 10. Contained within each of the conduits 10 is anelectrode 20. The electrode 20 is held out of contact with the conduit10 at its lower end by means of a strip of insulating material 21, whichis placed in a slot in the end of the electrode and held in place bymeans of a pin 22. The upper end of the electrode 20 is provided with athreaded portion 23, which is preferably reduced in size. This threadedportion 23 is screwed into an insulating-plug 24:. The insulating-plug 21 is externally threaded and in turn screws into a bushing 25, which isthreaded into the upper end of the T 11. The threaded end 23 of theelectrode projects beyond the insulating-plug 21 and is provided withnuts 26 and 27, between which is screwed a conductingstrip 28, whichelectrically connects all of the electrodes 20. This strip 28 isprovided witha binding-post 29, to which is connected one end of anelectric circuit 30, the other end of said circuit being connected bymeans of a binding-post 31 to one of the conduits 10. As the Ts 11,elbows 12, and nipples 13 and 14 are all made of conducting material,all the conduits will be electrically connected. Contained within thecircuit is a battery 32 or other suitable source of electric energy. Oneof the elbows 12 of each pair is provided with a drain-cock 33, by meansof which the impurities which settle to the bottom of the conduits maybe drained off.

The operation of my purifier is as follows: \Vatcr enters the left-handconduit 10 through walls of the conduit and the electrode 20. Theconduit 10 acts as the other electrode, so that the current passesthrough the water during its entire travel along the conduit 10. As soonas it has reached the end of the conduit the inlet-pipe 15 and passesdown between the it passes through the elbows l2 and nipple 13 to thenext conduit and is again subjected to the passage of the current. Inthis way it passes through all the conduits and is thus completelypurified. water may be regulated by means of the valves 17 and 18, so asto further insure the complete purification of the water.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. In a water-purifier, the combination with a plurality of conduitseach having an inlet and an outlet, said conduits being imperforateintermediate of the inlets and outlets, of electrodes arranged in saidconduits to leave free circulating-space for the water between theconduits and electrodes, and electrical connections connecting saidelectrodes and conduits with a source of electrical energy.

2. In a water-purifier, the combination with a plurality of conduits,each of said conduits having its outlet connected with the inlet of thesucceeding conduit so as to discharge the entire flow of Water therein,electrodes in said conduits, and electrical connections connecting saidelectrodes with a source of electrical energy.

3. In a Water-purifier, the combination with a plurality of conduits,each of said conduits having its outlet connected with the inlet of Therate of flow of the the succeeding conduit so as to discharge the entireflow of water therein, of electrodes arranged in said conduits to leavefree circulating-space for the water between said conduits andelectrodes, and electrical connections connecting said electrodes andconduits with a source of electrical energy.

4. In a water-purifier, the combination with a plurality of parallel andadjacent conduits, each of said conduits having its outlet connectedwith the inlet of the succeeding conduit so as to discharge the entirefiowof Water therein, of electrodes in said conduits, and electricalconnections connecting said electrodes with a source of electricalenergy.

5. In a water-purifier, the combination with a pair of imperforateconduits, the outlet of one of said conduits being connected with theinlet of the other, of a drain-cock situated at the junction of saidconduits, electrodes in said conduits but insulated therefrom, andelectrical connections connecting said electrodes and conduits with asource of electrical energy.

In testimony whereof I have hereunto set my hand in the presence of thetwo subscribing witnesses.

FREDERICK e. KUNE.
